Description
“Neutrope Japanese Invoice PDFs for WooCommerce” is a free plugin that generates Japanese-style invoice PDFs from your WooCommerce orders. It is designed for shops that need to deliver Japanese business documents (invoices and similar receipts) alongside their WooCommerce store.
Features (Free version)
- Invoice PDF generation (title, billing recipient block, line items, totals, consumption tax summary)
- One-click PDF output from the admin Order edit screen
- Customer-side invoice download from My Account (can be toggled on/off)
- Company name, address, and logo configurable from the settings screen
- High-Performance Order Storage (HPOS) compatible
- Japanese-language PDF output powered by mPDF
- Template (
templates/invoice.php) can be overridden from your theme
Planned roadmap (no committed timeline)
The following items are being considered for a future paid version. They are not implemented in the free version and there is no guarantee they will ship.
- Qualified invoice number (Japan invoice system)
- Per-tax-rate display (10% / 8% reduced rate)
- Receipt document
- Bank transfer information
- Payment due date
- Company seal, header note, recipient honorific
The free plugin exposes filters and hooks so the items above can be added by add-on plugins without modifying the core.
Credits / Third-Party Licenses
This plugin bundles the following third-party software and fonts.
- mPDF — GPL-2.0-or-later. The PDF rendering engine. https://mpdf.github.io/
- Noto Sans JP — SIL Open Font License 1.1. Used for the Japanese text in the invoice PDF.
Full license text is bundled atassets/fonts/OFL.txt. https://fonts.google.com/noto
IPA fonts were not adopted because they are not GPL-compatible; OFL Noto Sans JP is used so the bundle stays GPL-compatible. - DejaVu Sans Condensed — Bitstream Vera Fonts License / Public Domain.
Four files (DejaVuSansCondensed.ttf / -Bold / -Oblique / -BoldOblique) are bundled because mPDF requires them as the internal sans-serif fallback.
Full license text is bundled atassets/fonts/DejaVu-LICENSE.txt. https://dejavu-fonts.github.io/

Installation
Server requirements
- PHP 7.4 or later
- PHP extensions mbstring and gd (required by the bundled mPDF library)
- WooCommerce 7.0 or later, active
Steps
- Upload the plugin ZIP and activate it. The distribution ZIP already bundles the PDF library and the Japanese font, so
composer installis not required. - Confirm that WooCommerce is active.
- Open WooCommerce > Japanese Invoice PDFs and fill in your company name, address, and logo.
- Open any order from the admin and click the invoice button in the “Japanese Invoice PDFs” meta box.
For developers: the distribution ZIP excludes vendor/mpdf/mpdf/ttfonts via .distignore. If you run the plugin from source, run composer install first. The distribution ZIP can be rebuilt locally with powershell -File bin/build-zip.ps1. CI builds the same ZIP via GitHub Actions.
FAQ
-
Is WooCommerce required?
-
Yes. The plugin shows an admin notice and disables itself when WooCommerce is not active.
-
Can other people download my invoices?
-
No. Downloads from My Account require login, ownership of the order is enforced, and a nonce is verified.
-
Are PDFs stored on the server?
-
No. Every PDF is generated on demand and streamed to the browser, so there are no leftover files that could be linked directly.
-
Japanese characters look like garbled text
-
The plugin bundles Noto Sans JP (OFL 1.1), so no extra setup is needed. If you still see broken characters, verify that the PHP
mbstringandgdextensions are enabled on your server. -
Amounts display with decimals like “¥2,400.00”
-
The plugin follows the WooCommerce currency settings. To hide decimals for JPY, set WooCommerce > Settings > General > Number of decimals to 0.
-
Recipient name order and the “Japan” suffix in the address
-
Name order, honorifics (sama, onchu, etc.) and country labelling are roadmap items. The free version uses WooCommerce default formatting.
-
Can I customize the template?
-
Yes. Copy
templates/invoice.phptowp-content/themes/<your-theme>/neutrope-japanese-invoice-pdfs-for-woocommerce/invoice.phpto override it.

Changelog

1.0.0
- Initial release (free MVP).
- Invoice PDF generation, admin output, My Account download, settings screen, HPOS compatible.
